The carbohydrate distribu=on in mushrooms is reported changingreatlyinitsdifferentregionsduringgrowthandfrui=ng.Inthisstudy,the carbohydrate distribu=on in the compost and frui=ng bodies ofPleurotusostreatuswasanalysed.Sugar,polyol,polysaccharide,and chi=n content during different growth phases and in differentregions of the mushroom were determined. Results indicate thattrehalose, mannitol, and glucose were first accumulated in thecompost and then decreased during differen=a=on and growth offrui=ng bodies. Meanwhile, trehalose, mannitol, and glucose alsoaccumulated in the frui=ng bodies and primarily distributed in thes=pe,base,andpileusregion,respec=vely.Polysaccharidesmainlyaccumulatedwithinthepileusands=peregions,andchi=nwasmainly observed in the base region.
